Your questions didn't upset me; they're answered plainly in the article you're responding to.

The issue isn't people who own the property not being able to rebuild, the issue is people who were renting there likely being unable to afford to rent there after it's rebuilt, because the prices were previously low due to the age of the buildings, and it's almost entirely not zoned for multi-family dwellings.

If you aren't even going to read the article you're talking about, how are we supposed to interpret your questions, if not as being stupid?
